Larry at Mountain High. You just have to email or call after 1pm central time. I know its not as convenient as JensonUsa or Cambria, but his prices are usually much lower. Plus he's more of an LBS than an online retailer.
So I know Nashbar, Performacebike, Pricepoint and Jenson... anyone else reccomend an online site?
Cambria bike(CBO)is good. They have good sales and a blow out section.
Bluesky is good and will have unbelieveable deals every now and then.
Universal seems to run hot and cold with its customer service.
Greenfish has a few good deals.
Frankford bike has a deal every week.
ediscount bike and Icycles - buy up seconds and resell for cheap. both seem to have grown out of eBay. not much in Customer service.
Bikeman is good - check out his "dirty 30"
top of the Customer service pile is Larry at MountainHighCyclery - lousy website but just use the contact info and he acts like he's your brother in-law trying to get in good with the family.
